| Summary: | 碩士 === 國立中央大學 === 資訊工程研究所 === 92 === The reliable multicast protocol provides the efficient delivery and the reliability to the applications. Moreover, congestion control makes the transmissions adapt the sending rate to the available bandwidth and fairly share bandwidth with the popular traffic in the networks, TCP. There are many services built on the reliable multicast congestion control protocols. With the wireless networks increasing, the multicast services are more critical for the more mobile devices accessing the Internet. But the reliable multicast congestion control protocols are affected by the wireless high loss ratio to cause the low performance. This paper presents an approach, called PGMCCW, to alleviate the influence of the wireless losses. It can differentiate the wireless losses and the congestion losses on multicast and elect the proper feedback from the multiple receivers in the different networks. The detailed algorithm is described as the following chapters and the simulations demonstrate that this scheme is effective to improve the performance on the more popular wireless networks.
